CREEP FEEDING OF OATS TO CALVES ON PASTURE
This trial has two objectives. The first is to compare gains and cost of gains of calves, on pasture, that have access to oats in creep feeders, and calves on the same pasture that do not have access to oats. The second objective is to compare the performance of these calves in the feed lot.
Table 19 shows the average weaning weights and amount of oats fed in this trial for the five year period 1961 - 1965.

|Year||Average Weaning Weights||Av. Difference Lbs. Per Head||Lbs. Oats Per Calf||Lbs. Oats Per Lb. Added Gain|
|Creep Fed||Pasture Only|
|5 Year Av.||387.7||364.1||23.6||182||10.2|
Calves getting oats on pasture have been heavier at weaning in this trial in each of the five years the trial has been conducted. The average difference in weaning weight is 23.6 pounds per head. The creep feeding of calves did not affect the weight gains of cows appreciably during the pasture season. Table 20 summarizes cow weights for the 5 year period 1961 - 1965.

|Comparison||Average Weights - 1961 - 1965|
|Cows With Calves On Creep Feeders||1054||1099||45|
|Cows With Calves On Pasture Only||1041||1084||43|
A comparison has also been made of the feed lot performance of the steer calves from this trial. The ration fed to these steers in 1965 was 24 pounds corn silage, 1.0 pound alfalfa hay and 5.2 pounds rolled barley, plus 1 pound supplement. Rations fed in previous years were similar to the 1965 ration. These steers went into the feed lot at an average initial weight of 378 pounds and were sold when they reached about 1000 pounds. They were on feed for 340 days.
Table 21 shows the feed costs and carcass data for the 1965 trial. Table 22 gives the gains produced in the feed lot for the five year period, 1961 - 1965.

Creep feeding oats to calves on Pasture has resulted in an average gain of 23.6 pounds more per head at weaning time than calves on similar pasture, but which do not have access to oats. However, when these calves go into the feed lot, those not getting oats on pasture make greater gains than do the calves that were getting oats on pasture. The average difference for the five year period, 1961 - 1965, is 23 pounds per head.
The calves creep fed in the period 1961 - 1962 were not kept separate in dry lot which makes it impossible to get the feed per 100 pounds gain and the cost per 100 pounds gain for those years.
In the trials since that date separate trials have been set up so that information could be obtained. Table 23 shows the feed costs, dressing percent and grade of steers from pastures with creep feeders and steers from pastures without creep feeders for 2 year period, 1963 - 1965.

|Feed Per 100 Lbs. Gain||Feed Cost Per 100 Lbs. Gain||Dressing Percent||Average Grade|
|Pasture With Creep Feeders||1896||$12.21||57.24||Low Choice|
|Pastures Without Creep Feeders||1851||$11.80||56.70||High Good|
